If you have an older original GD77 look here for firmware flashing info
Before you begin and do anything ask yourself if you might ever want to reverse this?
If your answer is "maybe", "I don't know", or "yes" run a backup of the original firmware to reflash back to default
Detailed instructions can be found here
Why should I do it?
How should I do it?
Turn your DMR radio into a high power hotspot
It's important to keep all the downloaded and unzipped files in one easy to find folder on your computer
Unzip all compressed files
using
windows right click on the zipped file and select "Extract All"
NOTE: The firmware Bin file and the donor file are opened using the CPS only, do not attempt to open these files with your computer

Begin by downloading all 3
of the needed files then extract them and then run the new CPS
Step #1 Download the OpenGD77 CPS exe package here
at
the very end of the install make sure the check box to add cables
drivers is selectedStep #2 Download the OpenGD77 Firmware (for your radio) here
Step #3 Download the MD-9600 donor file (GPS or non GPS) here
Step #4 run the CPS, it's used to flash the radio
My example starter code plugs to get you started
This is important!
Grab the radio and plug in
the programming cable then into one of your USB drives, turn the radio
on,
if you hear the windows chime that means the radio and the computer are
linked up
Next turm the radio off, hold down the 2 side keys, check which of these two keys for your radio while holding them both down turn the radio on, you will hear the windows chimes and the LED will be flashing red & green you are now in DFU mode and ready to flash the new firmware.
